BUSHING FOR WOODEN LUG STICKS Filed May 28, 192

B zmm Jtfomey from the lug stickforthe purposes of re.-

I 2 With the foregoing and other ob ects H fl-"ti on to'make the lug stick used on this t f It has also been arosnrn naxmsfion rA'rEnson, NEW JERSEY Application filed May 28', it {This ,invention'relates to a bushing'yfor a] wooden lug stick and an object of thei1nven tion is a to provide a demountable bushing for the lug stick of a silk loorn'as t'oprevent I @wvearancltear about the opening whichconnects the lug stickwith the lug on a picker arm, and at the same time to prevent the:

' "stick from slipping.

. g Another object of the invention isto provide an easy means of detaching the bushing placing the same when becoming worn. e a Further objects of the invention are to i a provide a device of the character referred to,

" jWhlCh is strong, compact and durable, thoroughly reliable inits operation, very easy in its method of assembly with a lugstick and comparatively inexpensive to manufac- 111 1 view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompanyging drawings, but it is to be'understood that changes, variations and modifications may be resorted to, Without departing from the spirit of the claim hereunto appended. v V By reason of the character in the lightness ao in weight of silk, the loom used in'the weav- 1 ing thereof are constructedof very light materials. Wherever possible, it has been the custom of the loom manufacturers to substitute wood, such ashickory, ash or the like, 3c5g wherever metal parts may be replaced.

It has been the practice of loom manufacturers and particularly the type of Cromptonand Knowles silk loom and Northray ":Crompton loonrmade by Draper'Corpora-' yp of loom out of wood; 1 I From long experience it has been found that wood such as ash, hickory orthe like'has the proper resiliency with a corresponding 5i-"reduction in weight aspc'ompared with a metallic arm for the m etallic lug sticks, for I the same purpose.

7 found that a metallic lug stick isinsuificient for the purpose, because the natureof the operation of the lug stick i a y at 8-" It isitoibe understood thgt t efg nnsn neronwoolinnnoe" L Y i requires the maximum of resiliency and lightness. Considerable difliculty has been experienced: in the connection ofthe lug stick" with'the picker arm thatimpartsfthe motion thereto, by reason of thefact that the journal? opening in thejlug-sti'ck becomes worn to suchan extent that considerablewobbling 1 occurs in the stick, which causes many shut downs for replacement and repairs to :thef

loom. It has also been found that as soonias the opening becomes worn, thewobbling will cause the stick'tosplit and cause 'a smash up in the loom structure. "1 If; Bearing the foregoing in" mind and-1e ferringparticularly to the drawings, wherein the foregoingdefects are overcome-bythe construction in accordancewith this invention, and wherein like referenceicharacters denote corresponding partsjithroughout the several viewsd' {Figure-l is 'atragmentary side elevation of a wooden lug stick, illustrating an adaptation therewith of the device in accordancef with this invention. n I i Figure '2-is a fragmentary edge'view of thewooden {lug stick, illustrating the device adaptedvtherewith. f r l '1 Figuref'j is'aside elevation of the bushing .in accordance with this invention, detachedfrom the lugstick and having the securing nut, reinoveditherefrom, and I I F'gure 4 is afragmentary'sideele'vation of the lug stick and the pickerarm co'nnected together bylmea'ns ofthepresent invention.

'The other end of the" lug stick, (not shown in the drawings): is connected to the picker stick which is rocked upon an axis by the motion imparted by 6 and to impact With the shuttle whereby vthe same is driven back and forth across the silk loom. The-impact caused by driving'the V shuttle, back and" forth causes considerable vibration" of the rocking parts'and requires the maximum of resiliency in the parts, while at the same time'there is considerable-wear and tear thereon.

From long experience inthe, construction '7 ofsilk looms, almost universal'adaption of wood,such as hickory ash inathe formation of the lug stick, has resulted." T
